This seems fairly reasonable, for the partial withdrawal does not eliminate the initial reservation and does not constitute a new reservation; a priori, the objections that were made to it rightly continue to apply as long as their authors do not withdraw them.
Ello parece bastante lógico: el retiro parcial no hace desaparecer la reserva inicial y no constituye una nueva reserva; a priori, las objeciones que se le hayan formulado siguen, pues, aplicándose legítimamente mientras sus autores no las retiren.
